Typical Antenna Gain / Factor
This is calculated by reference to standard gain horn antennas, and cross checked with reference to the antenna beamwidth, with an estimated error of +/- 0.8dB.
Patterns measured using a linear source antenna , Horizontal / Vertical refers to the polarisation of the source horn.
On patterns the Red & Black trace = Horizontal polarised source, Green & Blue trace = Vertical polarised source
Pattern Cut Definition
Patterns are measured using a linear source antenna. The polarisation refers to the electric field polarisation of the source antenna.
Horizontal Cut (Cut 1) Vertical Cut (Cut 2)
Antenna viewed from back
- Red trace = Sweep with horizontal source polarization and antenna under test in horizontal cut (cut 1)
- Blue trace = Sweep with vertical source polarization and antenna under test in horizontal cut (cut 1).
